I'm not sure if this has been requested before, or if it's even possible, but I would love the ability to play against the computer again, especially in the HM game which seems to not get a lot of love sometimes.
Or, specifically for HM, a solo mode? I'm not sure how that would work but you...
I took 20-something pictures but only these three turned out. I'll have to go back some day when I have the time and a new camera.
Taken with my Nikon D80.
